Arrhythmia News and Research

RSS

An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.

Study shows why some stroke patients do not have abnormal heart rhythms

Scientists have shed light on why some people who have a stroke do not also have abnormal heart rhythms, even though their hearts contain similar scar tissue. Their results, published today in eLife, could help identify the best treatments for people who might be at risk of recurrent stroke, new heart disorders, or both.

Researchers report rare case of cardiac arrhythmias in a neonate with Turner syndrome

Doctors treating babies born with Turner syndrome need to look for heart rhythm abnormalities, in addition to the usual heart problems of high blood pressure or left-sided structural heart defects, according to Meena Bolourchi, MD, assistant professor of pediatrics at Boston University School of Medicine.

Scientists use ultrasound to map arrhythmic sites more accurately

Abnormal heart rhythms-; cardiac arrhythmias-; are a major worldwide health problem. Now scientists are using ultrasound for more accurate maps of arrhythmic sites in the heart for the improved success of ablation procedures.

Exposure to COVID-19 can cause rare but life-threatening pediatric condition

Exposure to SARS-Co-V2, the virus that causes COVID-19, can put otherwise healthy children and adolescents at risk for Multisystem Inflammatory Syndrome in Children (MIS-C), a rare but possibly life-threatening pediatric condition that can cause severe inflammation in organs like the heart, brain, lungs, kidneys and gastrointestinal system.

Artificial intelligence can predict risk of new-onset atrial fibrillation and AF-related stroke

A team of scientists from Geisinger and Tempus have found that artificial intelligence can predict risk of new atrial fibrillation (AF) and AF-related stroke.

SARS-CoV-2 does not infect the entire body in the same way, finds study

COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and "brain fog."

Researchers discover the role of a gene involved in cardiac rhythm

Researchers have used the zebrafish (Danio rerio) to identify the role of a gene involved in cardiac rhythm, which could help explain the fundamentals of what it takes to make a human heartbeat.

Researchers develop mobile EKG device that can identify patients at risk of sudden cardiac death

Researchers from Mayo Clinic and AliveCor Inc. have been using artificial intelligence (AI) to develop a mobile device that can identify certain patients at risk of sudden cardiac death.

Drug intervention may prevent heart damage caused by chemotherapy

There could be an intervention on the horizon to help prevent heart damage caused by the common chemotherapy drug doxorubicin, new research suggests.

Nocturnal respiratory rate of heart patients can help predict the success of ICD treatment

onditions causing arrhythmia are among the most common cardiac conditions. A study headed by Prof. Georg Schmidt of the Technical University of Munich has demonstrated for the first time that the nocturnal respiratory rate can help with an important prediction: It is an indicator of whether a defibrillator will help to extend the life of patients with arrhythmia.
